LUBRICATING DISCHARGE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 445,711, dated February3, 1891.

Application filed February 20, 1890. Serial No. 341,117- (No model.)

T on whom it may concern.-

Be it known that I, OLIVER. R. CHASE, a citizen of the United States,residing at Boston, in the county of Suffolk and Commonwealth ofMassachusetts, have invented certain new and useful Improvements inLubricating Dis charge-Nozzles for Soap, of which the following is afull specification.

My invention relates to nozzles of the class used to mold soap into barsor sticks of various shapes; and it consists of a nozzle especiallyadapted to be used as the outlet of a suitable machine for molding thesaid soap by pressure into a compacted homogeneous mass, the said nozzleserving to give the proper exterior shape to the mass as it is deliveredfrom the machine. For this purpose it is common to use a simple nozzleconsisting of an outlet-passage whose section is circular, elliptical,or of any shape in which it is desired to deliver the soap which ispressed through the same. WVith sucha nozzle it co mmonly happens thaton account of the friction of the plastic mass against the sides of thepassage as it is pressed through the center of the mass is forced outfaster than the outer surface thereof, resulting in a bar or stick ofsomewhat uneven shape, which is liable to crack or peel. To obviate thisdifficulty I have provided my improved nozzle with a lubricating device,the details of which are as hereinafter set forth, whereby the soap isevenly deliveredfrom it.

The accompanying drawing represents my improved nozzle and its fittingsin longitudinal section.

The spout or nozzle proper consists of two pieces A A, preferablyscrewed together, as shown at a, one of which is provided with thelubricating sleeve or collar B, made of wood or other hard stiff porousmaterial. The nozzle is coupled in any desired manner to the soapmolding and shaping machine, near the outlet thereof, with the part Apreferably in contiguity therewith. I have shown a female coupling Dfitting against a shoulder near the inner end of the piece A andprovided with the interior screw-thread cl, whereby it is screwed to theoutlet of the machine and the anyother form of coupling might beemployed. The passage through the nozzle is of such a shape incross-section as to mold the soap to the required form while deliveringit, being circular or elliptical or of any desired shape. It ispreferably made wide and flaring at the entrance end of the nozzle, asat a, and contracted to a narrower size at the outlet end for thepurpose of more compactly massing the soap as it is forced through it.

The lubricating sleeve or collar B, which is let into a suitable shapedrecess in one or the other two pieces A A, has an inner opening forminga smooth continuation of the passage through the nozzle. This collar iskept permeated with alcohol in any desired manner. To this end thesleeve or collar is provided with a grooveb passing around it, thealcohol being contained in a cup or reservoir C, screwed to the nozzle,and communicating by means of the narrow passage 0 with the groove 1)around the lubricating-collar. The alcohol which is contained in thegroove 6 permeates the pores of the wooden or other porous collar B andlubricates sufficiently the soap as it passes through the same andcauses it to issue evenly through the outer orifice A. At the same timethe lubricator serves to give the soap bar or stick as it is delivered aperfectly-smooth polished surface.

I use alcohol as a lubricator on account of its property of rapidevaporation, whereby the soap may issue from the nozzle in a dryeondition.

I claim A lubricating-nozzle for plastic materials, consisting of aspout provided near its outer end with a porous externally-groovedwooden lubricatingcollar held in a recess within said spout, the saidcollar having an inner open- 90 ing forming a smooth continuation of thepassage through the spout, in combination with a reservoir of alcoholcommunicating with the groove of the collar, substantially as described.

In witness whereof I have hereunto set my 5 hand.

OLIVER R. CHASE.
